Analytical Investigation of The Performance of Fluid Viscous Damper and Lead Rubber Bearing Isolator on A Multi-Storey Building

Abstract

Earthquakes are devastating natural events that can cause substantial structural
damage, often resulting in collapses due to inadequate seismic design. This study
investigates the effectiveness of two seismic protection systems: fluid viscous
damper (FVD) and lead rubber bearing (LRB) isolation, in improving the seismic
performance of a structure. The initial research did not include any base isolator
or link damper for earthquake protection. The results were then compared to a
similar investigation of the same structure using FVD and LRB isolation.
Significant differences in structural behavior were observed, with both systems
demonstrating improved performance in mitigating seismic forces. The findings
highlight the importance of incorporating advanced damping mechanisms, such
as FVD and LRB, in building design to enhance earthquake resilience in prone
regions. This study underscores the critical need for integrating such seismic
protection systems to reduce structural damage and improve safety during
earthquakes.
